71647-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71647-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,4 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71647-84:
(7*7)+(6*1)+(5*6)+(4*4)+(3*7)+(2*8)+(1*4)=142
142 % 10 = 2
So 71647-84-2 is a valid CAS Registry Number.
